Description: Length, 2.17 to 2.50 mm. 



Moderately robust. Head, prothorax, scutellum, and antennae 

 dark reddish brown; elytra, femora, tibiae, and tarsi lighter reddish 

 brown; pubescence somewhat conspicuous, fine, yellow on dorsal 

 surface, white laterally, on disc of prothorax and elytra sparse, slightly 

 denser at base of elytral interval 3, moderately dense on sides of 

 mesothorax and metathorax. Male beak short, stout, much shorter 

 than head and prothorax, one-third longer than prothorax, moderately, 

 evenly curved; in lateral view expanded ventrally at antennal inser- 

 tion, more or less attentuate to tip; in dorsal view expanded laterally 

 over antennal insertion, attenuate to apical third, slightly expanding 

 to tip ; punctures arranged in rows, deeper laterally, basal three-fourths 

 sparsely pubescent, apical fourth bare, smoother, moderately shining. 

 Female beak one-fifth longer than head and prothorax, seven-tenths 

 longer than prothorax, moderately, evenly curved; in lateral view 

 stouter in basal sixth, attenuate to apical two-thirds, there nearly 

 parallel-sided; in dorsal view moderately stout to antennal insertion, 

 attenuate to apical third, expanding to apex; finely punctured in rows, 

 deeper laterally, very sparsely pubescent in basal third, apical two- 

 thirds bare, apical third smoother, subimpunctate; beak moderately 

 shining throughout. Antennae inserted at distance from eye equal to 

 width of frons, of male at basal fourth of beak, of female at basal 

 sixth; first segment slightly shorter than next two, second segment 

 slightly shorter than next two, club 0.28 by 0. 10 mm. Eyes moderately 

 prominent; frons narrow, slightly wider than dorsal tip of beak, 

 abruptly declivitous behind eyes. Prothorax at base three-tenths 

 wider than long, middle narrower than base, apex three-fourths as 

 wide as base, slightly converging to middle, roundly narrowing to 

 constricted apex; in profile dorsal surface slightly arcuate; punctation 

 0.03 mm. in diameter, moderately shallow, interspaces rather convex, 

 slightly less than, to equal to, diameter of punctures ; basal fovea 

 moderately deep at middle, narrow, one-third length of prothorax.
